one of the most

important things for rendering an Unreal Engine

5 is the post process volume

if you don't know what that is

it's basically

a

giant Instagram filter that you can add to your scene

to add a post process volume

you can go

into your playsactors panel over here or the Q

sign right here and click and drag into your scene

now on average

this is the best way to deal with the post process

volume you're going to

scroll up to your post process volume settings

you're going to make sure

that the location is zeroed out

and then you're going to go to the search bar and type

U and B now what this is gonna do is basically

make

the post process volume and compets the entire scene

so wherever your camera is

then you're gonna be getting the

effects of the post process volume

I'm gonna take

this and move it to a folder at the top of my outliner

over here

I'm just gonna show you what it does really quickly

so I'm gonna clear out my search bar of the UN

found that we just change

and then if I go into let's say

my exposure settings right here

I can go in

and change how bright or how dark my image is

and if I were to leave this

camera and do the same thing

it's going to adjust the entire scene and make things

darker or brighter

so the post process

volume is the first thing that you should

pretty much add to any

cinematic that you want to make an Unreal Engine

in today's video

I'm going to show you some of the visual

effects that you can

add to your scenes using the post process volume

so the most

important ones that most people will end up using

in the post process volume are gonna be your bloom

lens flares and maybe some other

chromatic aberration and other lens effects

the first thing is bloom

if we turn on the bloom right here

by going into your post process volume and

under the lens settings

Bloom settings

we can select the method and we can change it between

standard and convolution

we're going to stick with standard for now and if we

select the intensity and bring it up

we can increase the glow

around the brightest parts of our image

so if we were to go in and change

this threshold we can say

what of our brightest parts is going to create

that glow now

standard and convolution

are interchangeable

but for cinematics a lot of people use convolution

the problem is that convolution is more expensive

as in you have to pay me money to use it

I'm kidding you don't need to pay me money to use it

instead

it just takes more rendering and processing power

in general if you're doing cinematics

I have not noticed a significant frame drop or

performance hit

so convolution is fine a lot of the time

again we can go in and change our intensity

we can also go into the advance tab and say hey what is

going to affect our convolution settings and

how detailed are we going to get with the

Bloom effect under

our post process volume

now if we leave this camera

we can

still see that we're affecting the rest of the scene

but in general

if you turn off the post process volume

we're going to turn off that bloom effect

and that's going to apply to all the other visual

effects that we're going to see in this tutorial

so I'm gonna go back into my camera

and if I look through

my main camera

by selecting this little button right here

now I realize I forgot to turn

my post process volume back on

we can see that we're getting a bunch of

glow and bloom and artifacts across our scene

that's gonna

bring me to the next setting that's super valuable

in the VFX settings of the post process volume

I'm gonna scroll down and we're gonna have this setting

called lens flares and we can find it right here

we can see that if we increase this value

or increase the bocus size

we're gonna get these artifacts

they're basically lens flares

that are hitting the lens in

this video game scene this unreal scene

so the reason

why you might have this is let's say you have a light

source in your scene and you want it to create

this cool looking effect

but the problem that I have with lens flares in Unreal

Engine is that it looks a little fake

if we were to pull up Shot Deck which is a resource for

gathering reference images from films TV

just some of the best work in the world in Hollywood

we can see that

a lot of the time

any lens flare that we're searching for

in this image database

we're only getting one light source and maybe a couple

lens elements hitting the frame

versus if we go back to Unreal Engine

we can see that we're getting a ton of

lens flares across our screen

now

you can adjust this by adjusting your scene and having

less light sources

you can adjust the threshold

you can go in and be like only one

thing is going to affect and create that lens flare

but on average

I don't like using the lens flares in Unreal

Engine because I just don't think they look

that realistic

granted if you're making a game

and this is what you need to use to create

the real time

experience effect

sure go ahead and use lens flares

in the post process volume

but I personally

don't like using it for my

work and commercials and

cinematics and stuff like that

so what I do with my Bloom

my Boca my

lens flares all that is I just set everything to zero

and then I just turn it off

I turn off the bloom

I turn off the intensity

I bring the threshold to a much higher number

I just make sure that I'm not going to get

any artifacts of bloom and lens flares in my scene

now when it comes to creating visual effects

a lot of the time artists will

dirty up a piece of footage an image

to make it look a little bit more realistic

versus a cinematographer

will do their best to try and have the most

perfect image on screen

and it's a balance of both

so we need to be really subtle with the next visual

effect I'm going to show you

the first and

perhaps the most prominent that a lot of artists

add on too much at the beginning

of a project is chromatic aberration

and if I turn this on here and I increase my value

we're getting this interesting little

red green blue separation of our image

now I don't like this

you can use visual effects if you want

you can add even a dirt mask and you can create some

smudges on your lens

I'm not gonna touch my lens because that's just gonna

look gross but you could

add this in the post process volume if you like

you just need to add a texture in this slot right here

I turn these off a lot of the time

because I don't think they look best in unreal

the only visual effects that I would even consider

adding if I really needed to is if I scroll down

to my image effects I have a vignette

and basically that's just going to

darken around the images of our frame to make it

focus on the center of our frame

but here's the kicker

if I jump over to Da Vinci Resolve

I would do all of these effects in Da Vinci

so I could do the same thing

I can go into my library and I can type in a glow

and I can create this glow effect

and now I'm getting that same bloom

or I can add a halation which is another type of

glow effect around

lens elements in a true camera

and we can get a much more interesting look

same thing with a vignette

I can add another node by hitting LTS on my keyboard

undo that because I turned off some nodes lt

on my keyboard

I can go into my power window

I can add a mask by selecting that node add mask

I can shape it up however I want

and then I can just affect what I need to effect

invert that

and I'm achieving the same thing that the post process

volume can do

in my other dedicated color grading software

now why would you do this

the first thing is that if you are dealing with

a small project

you can do a lot of the stuff

with the post process volume in Unreal Engine

well let's say hypothetic

you're dealing with a much bigger project with

different scenes

different shots

lots of different tools that you need to manage and

other artists in the scene

I don't like using this post process

volume setting because

a lot of that final

look elements such as chromatic aberration

or our lens flares our Bloom etc etc

that might need to be handled in da Vinci for

an entire project overall

so that is the post process

volume visual effect settings that I use

Bloom lens flares I turn them off

and I may adjust

my vignette if I want to but if you need to know

how to do that in Unreal Engine

that is where you would adjust your visual

effect setting in

the post process volume

I hope you Learned something from this video

if you did

let me know in the comments section down below

questions comments concerns

comment section is down there for that as well

and I will leave you with the final tip

eat one grammar protein

per pound of bodyweight and you'll make some games

go bye my friends

bye
